Air compressor

ldj · Nov 9, 2015

I have a old Kellogg air compressor model # a-320-a.
Just started having trouble with it not building up but 55# of pressure. I removed the head hoping to inspect and clean the reed valves. It hasn't got reed valves. It has some valves in the head and it would like to take then out and see if I can tell what is wrong. How do I get these valves out? I assume they are pressed in. Just by eyeballing the pistons fit in the cylinders are good, no ridge, pitting or anything bad.

Hello ldj,

One possibility would be a bad unloader valve. It usually fail to seal and leaks. Look for or listen for an air leak around the pressure regulator switch. There should be a small line maybe 1/4 in? going to it from the tank,

Guido.
